1 Overview of Portfolio Act 129, signed October 15 th, 2008, mandated energy savings and demand reduction goals for the largest electric distribution companies (EDC) in Pennsylvania. Pursuant to their goals, energy efficiency and conservation (EE&C) plans were submitted by each EDC and approved by the Pennsylvania Public Utility Commission (PUC). This annual report documents the progress and effectiveness of the EE&C accomplishments for Duquesne Light through the end of Program Year 2009. Compliance goal progress as of the end of the reporting period 1 : Cumulative Portfolio Energy Impacts The CPITD reported gross energy savings is 26,217 MWh. The CPITD verified energy savings is 3,642 MWh. Achieved 19% of the 140,885 MWh May 31 st, 2011 energy savings compliance target. Achieved 6% of the 422,565 MWh May 31 st, 2013 energy savings compliance target. Portfolio Demand Reduction 2 The CPITD reported gross demand reduction is 1.13 MW. The CPITD verified demand reduction is 0.16 MW. Achieved 1% of the 113 MW May 31 st, 2013 demand reduction compliance target. Low Income Sector There are 7 measures offered to the Low-Income Sector, comprising 11.5% of the total measures offered. The CPITD reported gross energy savings for low-income sector programs is 508 MWh. The CPITD verified energy savings for low-income sector programs is 510 MWh. (All low-income measures reported have deemed savings specified in the TRM adopted concurrent or after implementation requiring adjustment using a Deemed Savings Adjustment factor (DSA) that increased recorded savings from 508 MWh to 510 MWh.) Government and Non-Profit Sector The CPITD reported gross energy savings for government and non-profit sector programs is 6,000 MWh. The CPITD verified energy savings for government and non-profit sector programs is -0- MWh. Achieved 14% of the 42,257 MWh May 31 st, 2013 energy savings compliance target.

Duquesne Light filed its EE&C Plan on July 1, 2009 and received Commission conditional approved on October 22, 2009. Many programs were launched on or about December 1, 2009. Duquesne Light s PY 2009 EE&C program accomplishments were limited during this initial program year period of 6-month but significant ramp-up activities occurred. Business process teams were initiated soon after filing to begin the preliminary analyses for implementation of the EE&C plan. This was accomplished by reviewing existing processes and development of new processes to facilitate the full integration of the existing work flows with the new flows necessary to meet the Act 129 goals. A series of Request for Proposals (RFPs) were developed and released to the designated list of Conservation Service Providers on the PA PUC website in four separate flights. Evaluations occurred, interviews were held, references checked and finally contracts were signed. The signed contracts followed the approved regulatory format and were forwarded to the PA PUC for approval. Official notices to proceed were received in all cases. Training was given to the contracted CSPs for the Large Office and Primary Metals segments, the Small Office and Retail segments and the Mixed Industrial and Chemical segments on December 7, 2009 covering the overall EE&C program which had been branded as Watt Choices, the Watt Choices Website, the approved surcharge values for each customer class along with preliminary information on Program Management and Reporting System. Program Evaluation Measurement and Verification (EM&V) The following information was provided to the independent EDC program evaluator and incorporated into the EM&V Plan: 1. Full program descriptions, including operational and/or procedures manuals and activities descriptions and description of program service territory 2. Detailed descriptions of the Program Management and Reporting System (PMRS) tracking system and tracking system operations 3. A detailed description or map of how data in the tracking system rolls up to the quarterly PA PUC report 4. Program management and staff names, titles, work locations, phone numbers, fax numbers, and e-mail addresses 5. Program savings objectives 6. A program theory and logic model for each program. Program theory characterizes the relevant market(s) and how program activities are expected to change the behavior of the relevant participants in the market(s) to increase the adoption of energy efficient technologies and practices. The characterization of the market will include a description of the remaining technical energy and demand potential and the proportion of that potential that the program is expected to achieve at the conclusion of the current funding cycle 7. Name of firms participating in the delivery of the program or program component(s) (e.g., vendors, installers, specifiers, etc.) 3 For reporting participants, please report CFL participants separately from other program participant numbers.

For savings impact evaluation purposes, on June 22, 2010 an evaluation dataset was downloaded directly from PMRS that contained record of 9,180 customer actions taken to implement energy efficiency measures termed projects completed by Duquesne Light s EE&C Programs from initiation through May 31, 2010 (PY 2009). 4 Data supporting verification of program results for PY 2009 were recorded within the six month reporting period ending May 2010. The PY 2009 verification dataset results are shown in the following table: Program Participants MWh MW Residential: EE Rebate Program 2,861 723.2 0.0421 Residential: School Energy Pledge Program 4,750 1,898.6 0.7143 Residential: Refrigerator Recycling Program 252 452.7 0.0621 Residential: Low Income Energy Efficiency Program 1,296 507.9 0.1481 Commercial Sector Umbrella Program (1) 19 7.0 0.0014 Commercial Sector Retail Program 2 31.7 0.0061 Total 9,180 3,621.2 0.9741 (1) Project activity was 19 energy efficiency kits installed in residential dwellings served by commercial master-metered accounts The 9,180 projects include 8,326 (91%) energy efficiency kits containing residential measures (CFLs, night lights and furnace whistles) that the utility provided free of charge to program participants. The remaining 854 projects included 852 residential measures, and two commercial lighting projects. Because 9,178 projects out of 9,180 projects reviewed (99.98%) involved implementing residential measures in residential dwellings, PY 2009 verification addressed only PY 2009 savings impacts of the residential programs described below. Program performance and evaluation findings will be discussed in detail in sections that follow PY 2009 program verified savings impacts, project qualification and customer participation were very high (97-100%) resulting in the following realization rates and verified program savings reflected below: REEP SEP RRRP LIEEP Total DSA kwh Savings 766,512 1,913,405 452,736 509,684 3,642,337 DSA kw Savings 25.5 62.2 62.1 18.9 168.7 Net kwh Savings 744,612 1,858,736 439,801 509,684 3,552,832 Net kw Savings 24.8 60.4 60.3 18.9 164.4 kwh Realization Rates 97.1% 97.1% 97.1% 100.0% 97.5% kw Realization Rates 97.1% 97.1% 97.1% 100.0% 97.5% REEP Residential Energy Efficiency Rebate Program 4 Monthly data transfers to the SWE reflect 9,191 projects due to inclusion of 11 back-dated projects resulting from a data entry back-log associated with program ramp-up. Verification activities such as survey design, data requests, customer interviews, hard-copy review and quantitative analysis require a snap-shot of tracking system data. Verification was not performed on the back-dated projects but strictly adhered to the content of the verification dataset provided on June 22, 2010. The additional back-dated program activity will be addressed in PY 2010 verification activities. Duquesne Light EM&V Report for PY 2009 EE&C Programs is provided as Attachment A.

Program Changes Planned for 2010: First proposed change: SEP Residential: School Energy Pledge Program RRRP Residential: Refrigerator Recycling Program LIEEP Low Income Energy Efficiency Program 1. Residential: Refrigerator Recycling Program (RRRP): The RRRP is patterned after exemplary appliance recycling programs 5 to encourage residential customers in Duquesne Light s service territory to turn in their older operating refrigerators to be recycled. Removing an older, operating refrigerator can result in an energy savings of more than 1,728 kwh and reduce 0.24 peak kw. 6 To encourage participation in this program, this program provides a $35 check for the removal of the old refrigerator. The program is implemented by JACO Environmental that operates similar programs across the country and for other Pennsylvania EDCs. Based on recommendations by JACO Environmental and requests from Duquesne s customers, Duquesne Light is requesting to expand the program by adding Freezers to the program offer. The PA TRM documents the identical deemed savings for freezers under Section 4.5 Refrigerator/Freezer Retirement as for refrigerators. Similarly, recycling costs are identical. Duquesne Light proposes to change the title of the program to the Residential: Refrigerator/Freezer Recycling Program to improve customer service and promote greater program savings. Adding freezers to the program does not affect budgeting dollars already allocated to this program. Second Proposed Change: 2. PA Technical Reference Manual (TRM) Deemed Savings Measure Additions: Extensive collaborative work by the Bureau of Conservation, Economics & Energy Planning (CEEP), the Statewide Evaluation Team (SWE) and the EDC stakeholders in the TRM Technical Working Group (TWG) has resulted in the addition of many new deemed savings measures to the PA Technical Reference Manual. The TRM is updated annually through the development of Interim Protocols for the TRM. The updating process refines and improves deemed savings assumptions, adding new measures and streamlining program implementation processes. The collaborative process provides an opportunity for peer review of program measures under the guidance and oversight of the CEEP and SWE. 5 Based on the Pacific Gas & Electric 2008 ACEEE Exemplary Appliance Recycling Program (http://aceee.org/pubs/u081/res-light-app.pdf). 6 PA TRM Section 4.5 Refrigerator/Freezer Retirement, Table 4-5 Duquesne Light Page 4

Measures proposed to be added to Duquesne Light s approved EE&C Plan are shown below: New Measure Furnace Whistle Night light (LED) Night light (limelight) Heat Pump Water Heater (EF 2.0-2.3) Electric Water Heaters (EF.93 -.95) Refrigerator/Freezer Replacement* Smart Strips Effected Program REEP REEP REEP REEP REEP LIEEP REEP *This program is different than the recycling program noted in Change 1 above and involves complete replacement for low-income customers. Adding these new TRM approved measures offers our customers additional energy efficient products. All of the incentives in the Program are in the form of a rebate. The total incentive budget for the Residential Energy Efficiency Rebate Program (REEP) is $10.4 M and the incentive budget for LIEEP is $3.8 M for 2009-2013. Rebates on these products are offered on a first-come, first-serve basis. All rebates are tracked on a monthly basis against the total budget. To date, nothing has occurred to indicate oversubscription of rebates for a particular measure or rebate. In the event that certain measure rebates appear to becoming over-subscribed in relation to their derived benefit, Duquesne will seek Commission approval to limit or remove the measure from its Plan.

1.3 Summary of Evaluation Realization rates are calculated to adjust reported savings based on statistically significant verified savings measured by independent evaluators. The realization rate is defined as the percentage of reported savings that is achieved, as determined through the independent evaluation review. A realization rate of 1 or 100% indicates no difference between the reported and achieved savings. Realization rates are determined by certain attributes relative to one of three protocol types. Fully deemed TRM measure realization rates are driven by differences in the number of installed measures. Partially deemed TRM measure 8 realization rates are driven by (1) differences in the number of installed measures and (2) differences in the variables. Custom measure realization rates are driven by differences in the energy savings determined by approved protocols. The protocol type determines the data type that is sampled. 1.3.1 Impact Evaluation Explanation concerning the variance between monthly data transfers the Statewide Evaluation Team (SWE) and content of the evaluation dataset: Data transfers to the SWE were affected in response to the SWE s data request of 7/1/2010 on 7/15/2010. Duquesne Light s program year (PY) 2009 savings impact verification report was based on a download of program tracking system data downloaded on 6/22/2010 for activity shown to be installed in the tracking system through 5/31/2010. Program activity was entered into the program tracking system between 6/22/2010 and 7/15/2010 adding 11 projects with installation dates on or before 5/31/2010 for five customers participating in the Small Office Building Program and the Retail Stores Program. Data entry for back-dated projects reflects a data entry back-log associated with program ramp-up. Verification activities such as survey design, data requests, customer interviews, hard-copy review and quantitative analysis require a snap-shot of tracking system data. Verification was not performed on the back-dated projects but strictly adhered to the content of the verification dataset provided on June 22, 2010. The additional back-dated program activity will be addressed in PY 2010 verification activities. Evaluation, measurement and verification (EM&V) activities were performed on the following PY 2009 program activity: Program Participants MWh MW Residential: EE Rebate Program 2,861 723.2 0.0421 Residential: School Energy Pledge Program 4,750 1,898.6 0.7143 Residential: Refrigerator Recycling Program 252 452.7 0.0621 Residential: Low Income Energy Efficiency Program 1,296 507.9 0.1481 Commercial Sector Umbrella Program (1) 19 7.0 0.0014 Commercial Sector Retail Program 2 31.7 0.0061 Total 9,180 3,621.2 0.9741 8 TRM measures with stipulated values and variables. Duquesne Light Page 13

The evaluation dataset contained a record of 9,180 customer actions taken to implement energy efficiency measures termed projects completed by Duquesne Light s EE&C Programs during PY 2009. The 9,180 projects include 8,326 (91%) energy efficiency kits containing residential measures (CFLs, night lights and furnace whistles) that the utility provided free of charge to program participants. The 19 projects listed above under the Commercial Sector Umbrella Program (1) were actually residential energy efficiency kits provided participants residing in premises served by commercial master-meter accounts. The remaining 854 projects included 852 residential, measures, and two commercial lighting projects. PY 2009 verification activities addressed the four residential programs. Deemed Savings Adjustments As related above, deemed TRM measure realization rates are driven by differences in the number of installed measures. All energy efficiency measures delivered in the 9,180 projects were found to have deemed savings specified in the Technical Reference Manual 9 or interim updates to the TRM approved and adopted by the Statewide Evaluator (TRM). Consistent with Duquesne Light s EM&V Plan and the Audit Plan and Evaluation Framework for Pennsylvania Act 129 Energy Efficiency and Conservation Programs (Audit Plan) 10 analysis of tracking system values was performed to ensure claimed savings (tracking system savings values) reflected the approved deemed savings values. Several key measures deemed savings values were in the process of being developed and approved by the SWE either concurrent with, and in some cases after, project implementation. 11 As a result program implementers could not have known the values ultimately adopted. This created the need to adjust claimed/tracked measure savings to align with the deemed savings adopted. Tracking system values were compared with adopted savings values and a Deemed Savings Adjustment factor (DSA) was applied to claimed/tracked savings to bring them in-line with adopted savings values. The following table shows the result of this adjustment: Tracking System DSA Savings Program kwh kw kwh kw REEP 723,172 42.1 766,512 25.5 SEP 1,898,633 714.3 1,913,405 62.2 RRRP 452,736 62.1 452,736 62.1 LIEEP 507,932 148.1 509,684 18.9 Total 3,582,473 966.5 3,642,337 168.7 DSA Factor 102% 17% DSA dramatically reduced demand savings (kw) linked to removal of demand reductions for programmable thermostats and components contained in the EE kits (furnace whistles & nightlights), as well as severed reductions in CFL demand impacts through application of a 5% residential lighting coincident factor. 9 Pennsylvania Public Utility Commission, Technical Reference Manual for Pennsylvania Act 129 Energy Efficiency and Conservation Program and Act 213 Alternative Energy Portfolio Standards, June 2010. 10 GDS Associates, Inc., Nextant, & Mondre Energy, Audit Plan and Evaluation Framework for Pennsylvania Act 129 Energy Efficiency and Conservation Programs.

Sampling Plan As related above, all energy efficiency measures delivered in PY 2009 were found to have deemed savings specified in the TRM or interim updates to the TRM approved/adopted by the Statewide Evaluator. Based on low project-level variability simplified random sampling (EM&V Plan Section 2.8.1) was employed to achieve the desired level of confidence and precision.

While a process evaluation conducted during this time would have found many areas for process improvement, program management questioned the utility of such an activity. However, during the conduct of program sampling and the evaluation of program tracking system data evaluators learned key metrics were not being properly recorded by implementation contractors. This lead to adjustments in implementation processes which was communicated to CSPs and process revisions were made. Duquesne Light Page 15

The Public Agency Partnerships program targets federal, state and local governments, including municipalities, school districts, institutions of higher education and nonprofits (per Act 129). Local Government Partnerships were established through execution of a memorandum of understanding (MOU) by and between Duquesne and selected local governmental agencies. The MOU established working groups comprised of Duquesne and agency representatives and identified project areas within agency departments (and jurisdictional agencies); define project scopes of service; and establish project agreements to co-fund agreed-to projects. A partnership such as this was structured with Allegheny County and the City of Pittsburgh. Bi-monthly meetings have been occurring with the officials from Allegheny County and Duquesne Light which have partnered to provide over 100 municipalities the opportunity to have audits performed in their county facilities and provide opportunities to take action to save energy, money and the environment by participating in Watt Choices. In addition, several institutions of higher education have executed MOUs and have been involved in discussions and currently there are dozens of projects being evaluated as a result of these types of partnerships. Duquesne Light Page 34

3 Demand Response For Duquesne Light, the demand response goal translates into a demand reduction of 113 MW. Three demand response programs were proposed on July 1, 2009 for a total of 37.2 MW. The three include: 1) A direct load control program for air conditioners and water heaters for residential customers (18.6 MW) 2) A direct load control program for air conditioners for small and mid-sized commercial and industrial customers (7.8 MW) 3) A curtailable load program for large commercial and industrial customers defined as those facilities above 300 kw (10.8 MW) The proposed energy efficiency programs have a target demand reduction of 162 MW. Thus the total of demand response and energy efficiency is 199 MW, compared to the Act 129 goal of 113 MW. In March 2010, Duquesne Light issued RFPs for the demand response programs. The response in April yielded two bidders for the direct load control programs and one bidder for the curtailable load program. Meetings were held with all bidders in May 2010. The uncertainty over the establishment of approved measurement and verification protocols of the Statewide Evaluator may have accounted for the limited number of respondents. Currently, the bidders have been notified that the proposals are under consideration. They have been alerted that future discussions will focus on how to meet the goals of Act 129 once measurement and verification protocols are established. Plan of Action: 1) Participate on the demand response working group with PJM: Meet with other utilities, regulatory officials and PJM to develop consensus protocols for M&V of demand response programs. It is hoped the working group will have an acceptable protocol by October 2010. 2) Operate demand response programs with selected participants according to approved protocols beginning in the summer of 2011. 3) Operate and measure demand response programs in the summer of 2012 according to approved protocols. Duquesne Light Page 35

4 Portfolio Results by Program Duquesne Light prepared a comprehensive Evaluation Measurement and Verification Plan for its 2010-2012 Energy Efficiency & Conservation Programs (EM&V Plan). This EM&V Plan was reviewed by the Statewide Evaluator (SWE) and serves as the basis for EM&V performed of its Act 129 Programs. Additionally, Duquesne Light prepared a PY 2009 EM&V Report that was submitted and reviewed by the SWE. Both the EM&V Plan and PY 2009 EM&V Report went through a comment process with the SWE, whereby final comments were received and incorporated on August 31, 2010. These SWE reviewed and approved documents serve as the basis for and total EM&V activity performed, are referred to in the following section, and provided with this Annual Report for reference. 4.1 Residential: Energy Efficiency Rebate Program The Residential Energy Efficiency Rebate Program (REEP) is designed to encourage customers to make an energy efficient choice when purchasing and installing household appliance and equipment measures by offering customers educational materials on energy efficiency options and rebate incentive offerings. Program educational materials and rebates will be provided in conjunction with an on-line survey. REEP also provides energy efficiency measures in the form of energy efficiency kits provided free of charge to Duquesne Light customers attending targeted community outreach events. 4.1.1 Program Logic Program Theories, Logic Models & Performance Indicators are provided in the EM&V Plan at Section 1.2.5. Program logic diagrams are provided in EM&V Plan Appendix E, Figure E-2 for the Residential Energy Efficiency Rebate Program. 4.1.2 Program M&V Methodology The following describes the M&V Approach: Consistent with Duquesne Light s EM&V Plan Sections 2.5 and 2.5.1, the basic level of verification rigor was used for TRM deemed savings measures and measures with rebates less than $2,000 consisting of a six-step process: Step 1 Verification Checklist: A verification checklist includes data downloaded from PMRS and/or taken from hardcopy documentation for each participant installation or can be obtained by telephone or on-site visit. The following is a checklist of qualification, savings verification and installation verification activities applicable to the REEP: (Measure/Project Qualification) 1) Participant has a valid utility account number 2) Measure is part of the applicable rebate catalog or approved measure list 3) Proof of purchase identifies qualifying measure and is dated within the period being verified.
